This Thompson was created for the Hum3D Three D Guns 2 Challenge, and absolutely was a blast to work on. I managed to complete it in time fortunately, even though I didn't manage to get it exactly as I wanted it to be (mostly because my spare time was quite limited; Busy schedule).
Story behind this Tommygun (or shall I say...Chicago Typewriter?) can be found on my submission-page of the challenge:

It was also a fun way to discover the possibility of texturing some highpoly models, I might apply this technique in future projects as well.
